Unlock Chip AT89C5130A Flash

We can Unlock Chip AT89C5130A Flash, please view the Chip AT89C5130A features for your reference:

AT89C5130A/31A-M is a high-performance Flash version of the 80C51 single-chip 8-bit microcontrollers with full speed USB functions when Unlock Chip.

AT89C5130A/31A-M features a full-speed USB module compatible with the USB specifications Version 1.1 and 2.0. This module integrates the USB transceivers with a 3.3V voltage regulator and the Serial Interface Engine (SIE) with Digital Phase Locked Loop and 48 MHz clock recovery if Unlock Chip.

USB Event detection logic (Reset and Suspend/Resume) and FIFO buffers supporting the mandatory control Endpoint (EP0) and up to 6 versatile Endpoints (EP1/EP2/EP3/EP4/EP5/EP6) with minimum software overhead are also part of the USB module before Unlock Chip.

AT89C5130A/31A-M retains the features of the Atmel 80C52 with extended Flash capacity (16/32-Kbytes), 256 bytes of internal RAM, a 4-level interrupt system, two 16-bit timer/counters (T0/T1), a full duplex enhanced UART (EUART) and an on-chip oscillator after Unlock Chip.

In addition, AT89C5130A/31A-M has an on-chip expanded RAM of 1024 bytes (ERAM), a dual data pointer, a 16-bit up/down Timer (T2), a Programmable Counter Array (PCA), up to 4 programmable LED current sources, a programmable hardware watchdog and a power-on reset when Unlock Chip.

AT89C5130A/31A-M has two software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial ports and the interrupt system are still operating if Unlock Chip.

In the power-down mode the RAM is saved, the peripheral clock is frozen, but the device has full wake-up capability through USB events or external interrupts when Unlock Chip.

The AT89C5130A/31A-M clock controller is based on an on-chip oscillator feeding an on-chip Phase Lock Loop (PLL). All the internal clocks to the peripherals and CPU core are generated by this controller.

The AT89C5130A/31A-M X1 and X2 pins are the input and the output of a single-stage on-chip inverter (see Figure 5-1) that can be configured with off-chip components as a Pierce oscillator (see Figure 5-2). Value of capacitors and crystal characteristics are detailed in the section “DC Characteristics” before Unlock Chip.

The X1 pin can also be used as input for an external 48 MHz clock. The clock controller outputs three different clocks as shown in Figure 5-1:

· a clock for the CPU core

· a clock for the peripherals which is used to generate the Timers, PCA, WD, and Port sampling clocks

· a clock for the USB controller before Unlock Chip

These clocks are enabled or disabled depending on the power reduction mode as detailed in Section “Power Management”, page 155.
